For the non-invasive evaluation of patients suspected of having extracranial carotid artery disease, the non-invasive vascular laboratory at the Lahey Clinic, Boston, Massachusetts uses three tests. Carotid phonoangiography (C.P.A.) by itself is 60% accurate, the Kartchner-McRae Oculoplethysmograph (O.P.G.) by itself 80% accurate, and the Echoflow doppler arterial imager, by itself 90% accurate. These examinations are used for surveillance of high-risk patients and to determine the need for carotid arteriography. In a series of 94 patients, the combination of these non-invasive methods yielded one false negative and 2 false positive studies, for an overall accuracy of 95%.
对于疑似患有颅外颈动脉疾病的患者进行无创评估时，马萨诸塞州波士顿拉希诊所的无创血管实验室采用了三项检测。单独使用颈动脉血管音图（C.P.A.）的准确率为60%，单独使用卡特chner - 麦克雷眼体积描记仪（O.P.G.）的准确率为80%，单独使用回声血流多普勒动脉成像仪的准确率为90%。这些检查用于高危患者的监测以及确定是否需要进行颈动脉血管造影。在一系列94例患者中，这些无创方法联合使用产生了1例假阴性和2例假阳性结果，总体准确率为95%。
